Well, my truck died AGAIN! Ford has it now and found out the #6 fuel injector disentegrated. The techs can't find all the parts. This is the 3rd time this has happened. What could be causing this? What can be done to protect from this happening in the future?

 

same injector each time?

 

The first time it was the #1. The second and third time it is #6.

 

My guess would be low fuel pressure caused by restricted fuel filters or a fuel pump issue. Only way to know for sure would be to monitor fuel pressure.
